Does methane come up faster in sandy soil rather than clay?
Gas can travel through sand much further than through clay, or along the trenches of services where these trenches have been backfilled with crushed rock. ↑ Top of Page Treatment works on homes Is there a delay in the sealing of pipes and installation of monitors when requested? Sealing of pipes is only being carried out when methane has been detected in a house. This work is carried out as soon as practicable, dependent on resident availability to allow access to the house. Monitors can be installed as soon as possible after signing a consent form. If residents are concerned, a sweep of the house can be arranged within 48 hours. Should all houses have ventilation works undertaken? Victorian Building Regulations mean that many new homes already have adequate ventilation. However: • Cowl vents are being installed in some houses to provide further ventilation. • Where methane has been detected in cupboards, the point where the waste pipe penetrates the slab is being sealed with silicone.
